You're welcome, Jazmin.

To solve the given series of mathematical calculations:

1. Start by calculating 4 multiplied by 2 which equals 8.
2. Then, perform the multiplication of 16 by 2 which equals 32.
3. Next, subtract 30 from 50 which equals 20.
4. Finally, add 8 to 20 which equals 28.

So, the answer to the given series of calculations is 28.
